To all 'whom 'itfmay concern:

Be it known that I,PETER BAILEY, of

Smyrna, in t'he county of Clarke and State of Iowa, have inventedwa new and Improved Windmill; and I do hereby declare the following to be afull, clear, and exact description of the same, reference' being had to the accom- Pallyng drawing, making a part of this speci-` iication, in whichi Figure 1 is a top view,'and Fig. 2 is a sectional elevation. il This invention relates to a windmill constructed with am double wind-wheel, the two parts of which are mounted sideby side on the same shaft, one part being afxediirmly thereto, and the otherpart being placed loosely thereon, said parts being connected with' separate bevel-gears that engage with the same a cog-wheel, the latter being ii'xed upon a shaft that commlmicates motion to any train of machinery, the two `parts of the'wind-wheel revolving in opposite directions, and the apparatus being supplied with rudders that have adjustable wings, by regulating which the wind-wheels may be kept side to the wind, or

inclined to the wind, or edge to the wind, at pleasure, the wheels, when in this last-mentioned position, being stopped. t

Referring tothe drawing, a a are the two parts of the doublewindvwheel, the part abeing fixed upon a horizontal shaft, b, one end of which is mounted in avertical standard, c,

`and the other end of whichis mounted in a boX, d, that is secured upon a ring, e, which rests upon a ring, f, that is fastened upon the tops of four vertical standards, g', which are stepped The wheel a is fixed upon a tubular shaft, 7c, that incloses the solid shaft b. Abevel-gear,

l, is also iiXed upon said tubular shaft, and

t `upon the main shaft abevel-gear, my, is iixed, Vsaid gears connecting with opposite sldes of a cog-wheel, o, mounted at the top of a vertical shaft, p, stationed between the standards g.

The shaft p is stepped ina block, q, that forms part ofthe frame-work A. Nearthe lower end of the shaft p may be `mounted a bevel-gear, r, and a belt-wheel, .s.

driven by the gear r. i y i. y The wheels .a a revolve in opposite directions, and exert double 'the force upon the mechanism which theydrive that either alone could exert. The wheels are'providedwith radial wings t, `which are set 'at an inclination upward and outward tothe sides o f the wheels,

B is a shaft the wings of one wheel slanting in an opposite direction from those of the other, as shown in Fig. 1. l The wheels, therefore, only revolve when the wind strikes their sides, and are stationary as long as the wind blows against their rims. Y

In Fig. 2, a is a metal frame placed between a pair of vertical stay-rods, t, that are stepped in a block, fw, which is secured to the ring h, said stay-rods being at their tops secured in a brace, that is fastened at one extremity to the top of a frame, y, similar in all respects to ,the frame u, and placed at a quadrants interval therefrom, the other extremity` of the brace m being fastened to a rod, z, that forms a oontinuation of the frame y, projecting to the opl posite side of the ring c therefrom.

The frame y and rod z are secured in any 'suitable manner to the ring e. likewise secured at one point to the rame e, and at another point to the. bowed portion of the rod z. The whole mechanism that is -mounted on the ring e is rotated with the latter by the force of wind.

" The frames u and y are provided with vertical wings b', that are secured upon pivot-rods c.

The wings b' are all provided with transverse lugs f', extending horizontally from their central parts, which lugs are furnished with vertical pins al. The wings of each frame are connected by rodsl e', which rest on the lugs f', and are entered by the pins d. These .connecting-rods are notched, as shown in Fig. 1, so as to permit the free vibrationof the wings.

Connecting-rods g join the rods c to levers h', that are pivoted at their upper ends, one to the frame u, and the other to the frame y.

By means of the levers h' the wings b can be conveniently lopened or closed, all the wings of each set moving together.

A plate, 7c', secured to the ring h, between the two frames, and turned upward a suitable u distance at each end,- is provided with raelrspl` at each extremity7 for fastening the levers h in any desired position. e

The frames u y, whenthus provided with Wings, operate as rudders, in this` wise: Suppose the wings of the frame u to be closed and the wind to strike them fairly on the side. The consequence will be that the framel and wind-wheels will be whirled around until the outer sides of the wheels are presented full to the wind. If lthe wings of the frame y be meanwhile open, the wind will pass between them, and the wheels remain side to the wind7V and rotating in opposite directions as long,` as the wind holds in that direction. `If the wings of `the frame y be closed, then the wind will act upon them with the effect to prevent the wheels from being whirled so far as to lpresent their sides square to the wind,'and thewheels will stand inclined to the directiony of the wind,- oiquarte'ring2A Y* 4 To 'stop the wheels7 the wings of the frame must be' opened, and those of the frame jl] Closed, when'the wheels will whirl round till they will stop. v

they present their ril-ns to the wind,- and than Having thus describedmy invention7 what I claim as new, an'dde'sire -to :secure by Letters Patent, is-

v1. In a windmill, two oppositely-revolving wind-Wheels7 a a', mounted upon one shaft and connected with independent gears, which engage with one and the same mechanism, as

3. The combination of frame u, wings b', A connecting-rods e g',- lever h', and'rack l', as

described 4@ The combination of the wheels a a', rudders uy, rings efh, and standards g, as s'etfoitlL 5@ The combination of the' iframes' u y', braoe Y and bar z, as explained; I
